| Post subject: | 1964 Dodge Dart Gas Gauge |
Hi Everyone, I'm having a hard time figuring out why my gas gauge on my 1964 Dart Convertible/slant 6, won't work. I installed a new gas tank, and sending unit. Cleaned the electrical lead that goes onto the sending unit, and it seems to snap on tight. I'm very new at this, so can anyone recommend a series of steps for me to follow now, to try to fix this! I keep putting $5 to $10 in gas in the tank every trip out, just to make sure I have plenty of gas. I just drive this car locally here in New Hampshire, usually no more than a 50 miles radius, but would still love to have a functioning gauge. I appreciate any suggestions. Thanks! Mike[/img] |

There is supposed to be a metal strip with 2 clips on the end that is the grounding strap... one end clips on the nipple on the sending unit, and the other connects to the metal fuel line at the body and reaches just past your fuel hose connection on each end... if this isn't present the sending unit gets no ground and the gauge will not read... If you don't have one, you can in a pinch 'jury rig' one with a length of good gauge wire and two hose clamps... strip the end of the wire on both ends and clamp to the metal tubes on each side... some people will clamp it at the sending unit and screw the other end into the body.... Hope that solves the issue... if not, you may have to trace the sending unit wire from the trunk past the drivers side wheelwell, under the driver side carpet at the sill plate and up under the kickpanel to the dash....hopefully there isn't a break in the circuit there... |

Pull wire from gas gauge at sending unit then check voltage delivered by that wire. Should be 5 volts, but digital meter will probably run up and down 4 to 13 volts. This is due to the way old technology reduce 12v to 5v using contact points that heat up open then close to produce an average of 5 volts. Another test easier to perform is to disconnect at tank gauge wire, ground it and have a helper observe fuel gauge; it should swing from empty to full. Conduct this test just long enough to see gauge movement then disconnect ground jumper so as not to damage gauge. If you have voltage and grounding moves gauge all you need to do is ground the sending unit as described in other posts. Ground strap MF290 HERE, and two others available MF289 (ss) and MF710 an 8" steel strap. These are available from other vendors. |
